the problem with black screen was indeed due to not supported sphere format in html5 viewer. now with 1.18 it works.
Okay, but for better overall compatibility I would recommend using cubical images, e.g. created automatically by using the krpano tools.
is cursor change still not supported in html5 viewer in new krPano 1.18?
Yes, when something new will be supported, than this will be mentioned of course.
Best regards,
